The Minnesota Vikings open their three-day mandatory minicamp on Tuesday. The following is a depth chart based on how players worked during organized team activity practices. Injured players are in parentheses, with starters in their usual spots and all others listed at the bottom.

Rookie LB Michael Mauti, coming back from a torn ACL in 2012 with Penn State, went through stretching and participated in individual drills for the first time on Tuesday. He said he expects to be ready for a full practice when training camp starts on July 26.

WR Greg Childs also went through a limited regimen of individual drills, but he sat out most of practice as he continues his comeback from torn patellar tendons in both of his knee, an injury suffered in training camp last year.

DE Jared Allen (knee) and C John Sullivan (knee) both did rehabilitative work but didn’t participate in practice. The expectation is that both of them will be ready for training camp, Frazier said.

LB Nathan Williams, who had ankle surgery earlier this month, had his left foot in a boot.
